Class IfLessThanOrEqual

java.lang.Object
  org.jgap.gp.CommandGene
      examples.gp.paintedDesert.IfLessThanOrEqual

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable

public class IfLessThanOrEqual
extends CommandGene

A four argument version of if-less-than-or-equal (IFLTE) construct. If the first argument is less than the second argument, then return the third argument, else the return the fourth argument. Mimics the Lisp function from Koza.

Since:

3.2
